Evidence for myofibril remodeling as opposed to myofibril damage in human muscles with DOMS: an ultrastructural and immunoelectron microscopic study

One article on PainSci cites Yu 2004: A Deep Dive into Delayed-Onset Muscle Soreness

PainSci notes on Yu 2004:

From the abstract: “The myofibrillar and cytoskeletal alterations observed in delayed onset muscle soreness (DOMS) caused by eccentric exercise are generally considered to represent damage. By contrast our recent immunohistochemical studies suggested that the alterations reflect myofibrillar remodeling (Yu and Thornell 2002; Yu et al. 2003).” In other words, these researchers found evidence that what previously looked like microtearing of muscle tissue is actually probably just muscle tissue doing microscopic renovations — an adaptive process, not a repair process, and probably not painful in and of itself.
